The association of dental education with pediatric Medicaid participation

This study examines whether characteristics of dental education, practice characteristics and state Medicaid policies are associated with dentists' pediatric Medicaid participation.

Cross-sectional analysis of data about dentists' Medicaid participation in 2016, based on current practice characteristics and characteristics of dental schools they attended 5 to 10 years earlier. We analyze data about 22,500 general and pediatric dentists, drawn from the American Dental Association's Masterfile for 2016 and its dental school survey for 2009-10. The primary outcome is whether dentists participated in Medicaid-enrolled to accept Medicaid patients and payments-in at least 1 of their practice sites in 2016.

A majority (55%) of dentists accepted Medicaid in at least 1 practice site, while a quarter (24%) accepted Medicaid in all their sites. Dentists who attended schools with higher tuition rates were less likely to serve Medicaid patients at any site several years later (adjusted odds ratio [AOR] = .761). Dental schools' receipt of grants that encourage community-based training were associated with increased Medicaid participation at all sites (AOR = 1.22). Those practicing in rural areas also had higher Medicaid participation (AOR = 2.62). A 10% increase in Medicaid reimbursement rates was associated with increased Medicaid participation at any site (AOR = 1.24).

Dental school practices and state Medicaid policies are associated with whether dentists care for Medicaid patients. Changes in dental school or Medicaid policies, such as higher reimbursement rates, could help encourage more dentists to accept Medicaid patients, thereby increasing access to care.
